The burst signal was seen by all CGBM detectors.\n\nThe burst light curve shows a single pulse which starts at T=0.6 sec,\npeaks at 1.6 sec and ends at T+3.7 sec. The T90 and T50 durations\nmeasured by the SGM data are 1.4 +- 0.1 sec and\n0.5 +- 0.1 sec (40-1000 keV), respectively.\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1235826131/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University."
